Answer:
Explanation:
The absolute value of x is x.
y = 2x
Use the rise over run method.
2 is the same as 2/1. So, you rise 2 square up from the origin and then go over one, repeating the process. To do it in the negative zone, you just work backwards. Down two and left one.
You should have a diagonal line going from left to right that goes through the origin. Linear equations never end. They continue on forever, so your domain would be (-infinity, infinity) and your range would be (-infinity, infinity). Be sure to use the symbol for infinity instead of the word. The symbol, in case you do not know, looks like an 8 rotated 90 degrees.
